To all whom 42f/Jazzy concern:

Be it known thatl, LEsLiE P. GREEN, a

citizen of the United States, a'nd a 'resident` v,of the city ofChicago, county of Cook, and

btate of Illinois, have invented certain new Aand useful Improvements inScrapers, of

which the following is a specification.

`My invention relates to improvements in Scrapers especially adapted foruse inexcavatingwork and has for its` object the improvement of animproved construction of this charac-ter which is simple of construction and highly efficient in use; i Uther objects will appearhereinafter. The invention consists in the combinations and arrangementsof parts hereinafter vdescribed and claimed.

'The invention will be best understoodby -reference to --theaccompanying drawings forming a part of this specification, and inwhich,

embodying the invention,

Fig. 2 is a side view of the same, c

Fig. B is a transverse section taken substantially on line 3-3 of Fig. 2and showing the scraper as in act-ual operation.

Fig. 4 is a side view of a modified form of construction and,

Fig. 5 is a section taken online 5-5 of Fig. 4 and showing the scraperin position of use.

.The -preferred form of Aconstruction as illustrated in the drawings,comprises twol scraping members secured together inforwardly divergentrelation to' eac-h` other, said scrapingmembers being substantially incontact and secured together at their rear ends and ldiverging forwardlythere@ from. Each of said scraping members is preferably made of sheetsteel and `comprises a substantially vertical upper. por"- tion 4 and aninwardly and downwardly in clined lowerportion 5 as indicated. Saidscraper members are rigidly secured together at their rear ends where'they are y provided "with a vertical lip or iange 6 as shown.

vhaving two perforations 7 for the reception of a clevis 8 to which"cable 9v is attached. At their lower edges` thescraper portions 5 arereinforced b'y wear 'plates 10 At their forward portions the scrapingmembers are provided with forwardly extending vertical keel plates orguides 11 secured to the forward edges of portions 4 and also secured tothe forward Fig. 1 is a perspective view of ascraper Eppneation'nled:riin'e' e, 1`ea1.fseiai Eo.

upper vedgesof the 'portions' almglinesIv 12 as indicated. The forwardedges of the" guide plates 11 are provided with a plurah'ty of openings13 for the reception. of.

.,clevlses 14 for-'attachmentto the cables 15 as shown and cover portion16 Ais arranged` across the upper portions of the sides 4 and providedwith verticai vflanges 17 arranged against the inner sides of themembers 4 and secured thereto lby means of bolts 18. The bolt holes forthe bolts 18am-so arranged that the cover portion 16 may be removedandreversed in position as indicated in Fig. 3 and whereby the capacity ofthe scraper may be varied.

ln ruse the scraper is utilized by drawing the same in vone directionover the area to be excavated.v by means of the for- `ward cablesl 15.A'During such movement the scraping portions 5' will dig up the earth orother material and gather the same in the enclosure .between thescraping members. When this enclosure becomes sub-- stantially filled,the cover portion 16 will rest and ride upon the `material therein,

thus in effect, elevating the scraper from digging contactA andpreventing any further digging.A For this purpose the covermember 16should be of sufficient area and eX tent tocause this-riding actionwhich will scraping membersfis substantially open at its-front andbottom, the contained material will be deposited at this point and vthescraper is then returned ,for a new load. By removing the cover portion16 and reversing the same 'in position, f the capacity of the scrapermay be varied to the extent `of the d'epth of the flanges 17. The keelor guide plates' 11 serve to maintain the travel of the scraper in yasubstantially straight forward direction preventing side swerving,stiften the construction, and also tend to hold the load or chargetherein during forward travel. i p

In 'the' modified form of construction illustrated in Figs. 4 and 5, thescraping titi members were made fiat and are arranged to slope inwardlyand downwardly from their ytops to their bottoms.

i/Vhilev l have illustrated and described the preferredl forms otconstruction for can rying my invention into eiect, these are capableoiEvariation and modification without departing fromthe spirit of theinvention.' l, therefore, do not wish to be lim- Having described myinvention, what `l' claim as new anddesire to'secure by Letters Patentis:

1. A scraper comprising scraper'members' associated together to formlthesides of an enclosuresubstantially open at the front and bottom; anda cover portion forsaid enclosure vertically adjustable #with relationvto said scraper; members and adapted and arranged to rest-upon materialgathered be tween said scraper members cause 'said scraper to ride uponsaid material'when substantially iilled, substantially. as ldcscribed.i. A ZA scraper comprising scraping members having inwardly anddownwardly in-l clined lower portions; and a cover portion extendingover the space between said scraping members to rest upon materialgathered thereby and cause said scraper to ride upon said material whensubstantially filled, substantially as described. l

3. A scraper comprising scraping mem- 'bers arranged in forwardlydivergent relation to each other and a cover portion eX tending betweenthe upper portions of said` scraping members to rest upon materialgathered between them and cause said scraper to ride lupon said materialwhen substantially filled, substantially as described.

4C. A scraper comprisii'igscraping members arranged in 'forwardlydivergent rela .tion to each other; and a cover portion extendingbetween the upper portions of said scraping members and adjustablysecured thereto to rest upon materialgathered between said scrapingmembers and cause said vscraper to ride upon said material whensubstantially Afilled, substantially as described.

5. A scraper comprising scraping mein- `bers having substantiallyvertical upper 1 portions and inwardly and downwardly inclined lowerportions; and a cover portion extending between the upper portions or"said scraping members to rest upon material gathered between them andcause said scraper to ride upon said material when substantially filled,substantially as de scribed.

6. A scraper comprising scraping inemi l readers bers arranged inforwardly divergent relation toeach' other and having substantiallyTverticalV upp'er portions and inwardly and downwardly inclined lowerportions; and a cover portion 'extending between the upper portions otsaid scraping members and adjustably secured thereto to rest uponmaterial gathered. between said scraping members'and cause said scraperto ride upon said material when substantially iilled, sub- Astantiallyasvriescribed.

7'. `A scraper 'comprising scraping mem! f bers associated together toform the sides of an enclosure substantially open at the front andbottom 5. and a cover portion extending` between the upper portion ofsaid scraping members, said cover portion being provided with verticallyturned flanges titting against the inner sides ot Said scraping membersand detachably secured thereto, said cover member being reversiblebetween said scraping members, substantially as described.

8. scraper comprising scraping memlbers arranged in forwardly divergentrelatioiilto each other and having substantially ive'rtical-upperportions and inwardly and downwardly inclined lower portions; and acover portion 'extending between the upper portions otsaid scrapingmembers, said cover portion being provided with vertically turnedflangesv at its sides fitting against the .inner sides of said scrapingmembers and detachably secured thereto, said cover member beingreversible between said scrap- Lingmembers, substantially' as described.

9. A scraper comprising scraping meiir .bers arranged in forwardlydivergent. relation to eachl other.; and a cover portion eX- tendingbetween the upper portions of said scraping members and Jforsubstantially the full length thereof, substantially as described.

10. A scraper comprising scraping members having inwardly 'andidownwardly inclined lower portions-g and a cover member extendingbetween the upper portions and substantially theV full length ot Saidscraping members, substantially as described.

1l. A scraper comprising scraper members arranged in forwardlydivergentrelation to each other and having substantiall)7 vertical upperportions andinwardly and downwardly' inclined lower portions; and acover member extending betweenthe upper portions and substantially theJfull length ot said scraping members, substantially as described.

n testimony whereof l have signed my naine to this specification in thepresence ot two subscribing witnesses.
